Hi,
Sorry for the long delay in my response, it took me a while to get back to
this.
when I try the command in msys bash I get
PID PPID COMMAND
5324 1 /msys/bin/bash
5976 5324 /msys/bin/bash
6184 5324 /msys/bin/ps
But when I try in command line, I get
Can't find string terminator "'" anywhere before EOF at -e line 1.
It seems that perl runs new process under a windows command prompt, and not
under bash.
So the quotes are not parsed correctly
Thanks,
Tzafrir
